Is there a lock screen on Linux-based systems?
When the screen is locked, the user should enter a PIN code to enter back. Like the PIN screen lock on an iPhone.

I don’t know if you are looking for a tool or library to do this. There are quite a few DE independent options:
They are opensource so you can take a look at code if you are looking for a programatic way to do this.
For library you can look at xlib for all interaction with X. XLockDisplay is the function that you might want to use.
